K2-K6:
Have you tried spraying the intake rubbers from carb to head with something like wd 40 while running to check for air leaks?

Check that the tips of the mixing screws are fine, they must have a conical tip, you turn until reaching the stop without forcing it, and then in a counterclockwise direction unscrew about 2 turns, the 4 equal, with rolling 100 meters You will notice if it drowns or lack of gasoline, if when placing the carburetors they lose their blows, a float may be hooked and not cut the valve, what jets do you have? You say that the needles are at their maximum height, that will only influence after 1 / 2 throttle up to the wot. mark the stroke of the fist in 1/8, 1/4, 1/2 and 3/4 and check how the motorcycle behaves in each position

Would low compression cause slow running issues? I'm struggling to think of anything else that's causing my problem. It runs lovely over 3000rpm sits at 60 70 mph great, it also ticks over at 900rpm when cold, but once hot either dies or revs itself up to 3500 rpm. 🤔🤔🤔
